Gait Analysis
Why Gait Analysis ?
Your foot is in contact with the ground
for about 0,8 of a second when walking
and
about 0,25 of a second when running
Imagine trying to determine normal or abnormal function of the leg with the naked eye in a quarter of a second. This is to difficult even for the most experienced practitioner
What Is Gait Analysis?

Gait is the pattern in which you walk or run: Your personal step by step "cycle"



Gait Analysis is a method for examining the "cycles", looking for variations, and abnormal movement patterns

The Test Has Several Components:
Gait Kinematics
As the movement of the person walking is recorded by high speed video cameras a reconstructive digital model is created in order to calculate joint motion in each plane.
Gait Kinetics
Kinetics are the forces which act across the joints.
The ground reaction force of each foot strike is measured as the person walks through the force plate. The magnitude of the ground reaction forces can then be calculated during different phases of the gait cycle.
Surface Electromyography (SEMG)
SEMG provides information about how the muscles work during walking. We can use the SEMG data to see how each muscle acts and how it contributes to the gait abnormality.
Foot Pressure
Foot pressure is measured during walking through a specialized instrumented treadmill . This enables a visualization of foot mechanics, timing sequence of gait cycles , 3-D pressure distribution and a visualization of center of pressure ( gait line).
How Is Gait Analysis Performed?
The subject walks on the specialized walkway or instrumented treadmill. The markers are tracking motion by multi camera motion capture system . Force plates in the walkway/treadmill gather kinetic data as the subject walks over them . A computer workstation equipped with motion analysis software permits the gait data to be analyzed. After processing the gait analysis , report including video clips of your gait cycles is produced. PICTURE 4 (Picture of subject walking through treadmill).
Who Needs Gait Analysis?
Gait analysis is extremely diagnostic for patients with lower extremity problems , patients who have pain during walking or running. People with knee, hip , foot and ankle pain. Athletes and runners. As well as people who have balance and instability issues during walking. Some categories of low back pain patients could also benefit from gait analysis.
Clinical Significance of Gait Analysis

Whether you are an active sportsman, recovering from an injury or simply want to enjoy pain free mobility, gait analysis can provide valuable data for you recovery.
Gait analysis benefits include:

  • Provides biomechanical data about efficiency of your mobility
  • Provides functional reasoning why you have pain
  • It may identify the origin of your pain disorder not explainable by radiological imaging
  • Defines treatment protocols
  • Speeds up rehabilitation
  • Provides objective monitoring of your recovery
  • Can rule in or rule out orthotic prescription by identifying if foot problem comes from faulty mechanics at the hip or at the foot
  • Gait and running analysis Is irreplaceable clinical tool in diagnosis of sport and verse injuries
  • Gait analysis can help to maximize your performance , eliminate biomechanical deficiencies and improve strength
What Pathologies Are Particularly Useful to Diagnose and Treat Utilizing Gait Analysis

All running and overuse conditions of the hip, knee and foot !!!

  • Hip Femora Acetabular Impingement ( FAI)
  • Hip arthritis
  • Hip instability
  • Patellafemoral pain syndrome
  • Osteoarthritis of the knee
  • Tibialis posterior tenon dysfunction
  • Plantar fascitis
  • Peroneal tendinitis
  • Metatarsalgia
  • Medial arch pain
  • Ankle instability
  • Shin splints
  • Stress fractures in the foot or leg
  • Some types of back pain
